But if you aren't sure you need to support this, then just throw an error
(Float16 is relatively new and AFAICT only useful in specialized
applications because of the precision limit, which is why support is rare)
If you are sure you (a) need it but (b) only need
You can pull the significant bits and the exponent values out of a Float16
and then use those to compute the value as a Float32:

Aha, that fixed it!
I'm running into one issue though. What do I do with the data when it's a
"Float16" type? C++ has no way to represent a 16-bit float, so I'm having
difficulty converting it to a regular 32-bit float.

The issue here is that `jl_array_eltype` is already returning a type.
`jl_typeis(v, t)` becomes `jl_typeof(v) == t`, so your checks become:
jl_typeof(array_type) == jl_int64_type
But
jl_typeof(array_type) -> DataType
Instead, either do the equality check directly:
array_type == jl_i
I apologize for the formatting, that should be:
jl_value_t *ret = jl_eval_string(code_string);
void* array_type = jl_array_eltype(ret);
jl_array_t *ret_array = (jl_array_t*)ret;
if (jl_typeis(array_type, jl_int64_type)) {
long *data = (long*) jl_array_data(ret_array);
}
else if (jl_typeis(array
Awesome, thanks. Could you show how to use it in a minimal code example?
Here's what I'm currently trying, but it does not appear to be working:
jl_value_t *ret = jl_eval_string(code_string);
void* array_type = jl_array_eltype(ret);
jl_array_t *ret_array = (jl_array_t*)ret;
if (jl_typeis(array
In addition to this, CxxWrap.jl has some additional convenience classes to
work with Julia arrays from C++, see
